y Be it known that we, ERNEST EDGRDAG- fLI'sH and WALTER LEONARDr LoRKiN, both v`subjects', ofthe ,King l siding at. 2 and v3 Norfolk street, Strand, in thfe countyl of London, England, have in-v ventedl certain-'new4 and useful Improveof Great Britain, re-

ments-fin' orRelatin'g to' WVindingvMecha- ',nism, of which theffollowing' isa speci-fica tion. e This invention: relates to hand operated' or power drivenwinding mechanism and is particularlyk intended for hand actuated `brakeimechanismjof'electric cars and other vehicles, such fas that ofthe kind wherein? 'the operating hand wheel or hand lever vis connectedto 'the .chain drum of the brake '.by means ofgearing, 'and inl which two 'of the hand lwheel or lever.;

' stops arefemployedlthe cooperation of which l limits the unwinding or releasing movement The chiefobjects ofthe invention are "to provide brake mechanism whichas compared with such mechanism heretofovcon- -structed will be more leliicient in its action,

more readily VVassembled and dismantled, of

'less weight, more compact land capable of y being more readilyadjusted.v

on a loosely mounted cover E.` This cover a is also 4formed with a stop Ez (Figs 2. and 3) adaptedto coperate with a pin F cari ried by a disk F (Figs. 2 and 4) which is loosely mounted between the .cover Ey and the ratchet wheel B2. This disk is provided (Figs. 2 and 5) From the above description it will be seen that the parts referred to constitute a form of lostl motion arrangement similar to that set-forth :in the specification of our applijustment being obtained by the placing of the stop D4 in one or .other of thefflour pillars D3. When the shaft B is rotated after'having moved through nearly a fcfoniplete revolution causes the pin Btherefon to coperate with the end of the'slotl F2 thereby moving the plate F; After a time the pin F engageswith the projection E2 and the cover Ey is thenmoved until the projection E comes into contactk with the fixed. stop D4. By thesey means' the shaft B can move through approximatelygthree complete revolutions in applying thebrake andwhen the brake i's released the' chain Hdrum will be stopped inthe original pre-f vdetermined position. It will be observed that by reason of the stop D4 being mounted in one ofthe pillars D3 it can be readilyI removed from the topI of'the car platform so that it'can be pla'ced-in another of the pillars when desired. The plate D is formedl with 'lugs D5 "('Figs.. 1 andG.) by

which itcanbe suitably fixed-to the-car.

platform. p

Arranged beneath the carfplatform is a plate G having a boss G that bearsfagainst the lower face of the boss D; This boss G is formed lwith a hole to rotatably receive the lower end ofthe' shaft B and onk the with a curvedslot F 2 in which a pin B" carried by the ratchet wheel cation Serial No. 792,203, the" requiredf adi 570' 'the `ratchet wheel B? moves with it :and I lower'end'of this shaft' the pinion kC- is mounted, the said pinion being prevented fromfalling by a pin @passing transversely through :the shaft B, onbyother suitable means. In order to prevent'the pinion lC from fallingeven in the event of 'the pin c breaking orv becoming detacl'ied,y theisaid pinion is provided with an upper flange o the bolt Cs and. pin g engage with the PM' bearing upon the upper face of the gear B in order to brin with or may! beconnected to the chain drum C and these two parts may be held -in position-by a bolt C3 passing through the car platform and the drum .C and through a boss Gr2 on Athe plate G. One end of the said plate G is formed with a pin g and the other end with twd curved slots g (Figs. 6, 7 and 8) concentric with the axis of the boss G. A bolt d or the like (of which two are provided one passing through each of the lugs Dl of the plate D1 and throiigh each of the slots g1) may beemployed for holding the plateG in position. Prior to attaching the plate G tothe car platform, the said plate may be rotated about the axis of the shaft the drum C more or less into position -to suit the line of draft of the chain. This determines the`points at which form, while the slots g enable the adjustnent of the plate G to take place after which the bolts d are tightened to assist -in maintaining the plate in the adjusted position.

`Pre erably 'formed -in one casting with the plate G 1s a yoke H which may be forked as shown in Fig. 8 and which serves to su port thelower end Aof the pin C'. T e aforesaidslots g pass .through the ends of the forked members of this yoke. Suitable webs h, h, (Fig. 1) may be cast on the yoke to -ve it the required rigidity.
